Inductive Proximity Sensors
An inductive proximity sensor works with a high
frequency oscillating circuit that creates an alternating electromagnetic field on the active sensor surface by means of a coil. When a metallic object nears this field a damping occurs in the oscillating circuit. If this damping exceeds a threshold value, a switching signal is generated.
Basically they detect metal - in general the bigger the inductive proximity sensor the longer the range. We have a range of suppliers and many different options - the easiest way to find the best product is to email Powelectrics with your requirements and we will put forward what we consider to be most appropriate.
The EGE range of inductive proximity switches
EGE offer special inductive proximity switches for special applications. Focus is on TROPICAL switches which exceed IP 69K with a temperature range up to +120 °C and is optimally suited for corrosive environments. High temperature switches up to 160 °C are also available.
There are high temperature inductive proximity switches that can be used in temperatures up to 250 °C, and low temperature proximity switches that work down to -60 °C and applies to the POLAR switches.
Inductive proximity switches with long range having switching distances up to 170 mm and sensors resistant to rolling oils made from PTFE, PP or PEEK are also available for the food industry. Intrinsically safe ex-classified sensors according to ATEX and compact dust-EX and gas-EX sensors are included, and there are even some standard units..!
The Contrinex range of inductive proximity switches
Inductive proximity switches from CONTRINEX benefit from their patented Condist® 
oscillator giving significantly better stability with respect to environmental influences, in particular, temperature.
The improved stability permits the switch point to be further away, leading to longer operating distances. The subsequent assemblies are no different from those of inductive proximity switches with standard operating distances. Material dependency is similar to conventional oscillators.
The Contrinex range of inductive proximity swithces include all metal units, which are of particular use in harsh environments or when the switches are subject to collisions with other objects.
